DRIVING-GEAR FOR ELECTRICALLY- ACTUATED TRUCKS OR RAIL-CARS.

Specification of Letters Patent.

Patented July 9, 1912.

Application filed February 21, 1911. Serial No. 610,079.

To all whom, it may con ern lie it known that l, \VAL'rnn J. Srxxoucn, of Philadelphia, in the county of Philadelphia and State of Pennsylvania have invented Certain new and useful Improvementsin Driving-Gear for l lleetrieally-ixetuat'ed Trucks or Rail-Cars, whereof the following is a specification, referenee being had to the. accompanying drawings.

My invention is especially designed fer electrical ears and'eonsists of an axial driving gear by means of which the motion of the motor shaft is transmitted to the axles of the truck in the median plane of a true]; (or of a. rail car), with ave-idanee of the lateral strain or torque to whieh the truek (or frame) of a car is subjeeted by driving gear by which power is eonununieated to the axles elsewhere than in the median plane.

According to my invention, 1, mount upon the truck or frame. of the ear. a motor with its shaft lying longitudinally in the median plane thereof the motor oeeupying a central position. This shaft drives at both ends. a bevel gear mounted on the same axis. whieh gears with a bevel pinion mounted on a eountershaft earrying a pinion lying in the median plane of the truck whieh gears with the. driving gear of the axle. lying in the same plane.

To the :weonumnying drawings. Figure i. is a plan view showing a truck provided with a driving gear embodying my invention. l ig. ll. is a horizontal section through the parts of the gear adjaeent to one of the axles.

Referring to the drawings. the motor I. is slung centrally upon the truek. with its motor shaft 2. lying longitudinally in the median plane of the truek. lioth ends of the motor shaft are projected and employed for driving respeetively the two axles of the truck.

The driving gear for the eonneetions is the same. for both axles and a description of one will therefore sutiiee as a description of both. universal joint-i1. of standard eonstruction is interposed in the shaft The extension 4. of this shaft beyond the Hillversal joint is provided with a. square head i fitting in a squared socket 6, formed in the universal joint. thereby allowing for alteration in the effective length of the m0- tor shaft. The extension 4, rests in suitable hall hearings 7, and carries at its extremities a bevei pinion 10. which meshes with a bevel gear 11 set upon a eountershaft 1:. This eountershaft is mounted in suitable hearings in a box or housing 1; slung upon the truck, and carried prefe ably partly by the wheel axle with which it is associated and partly by a cross harm, running between the sides of the truck, to whieh it is bound by bars or webs 9.

in the median plane of the truck, the, eonntershaft l2. earries the pinion 15, which meshes with the gear 16. which surrounds the axle 17, also in the median plane of the tlllt'k. This gear 16, may he set directly upon the axle, but I prefer to interpose a ditl'erential gear as indicated at 18. By the use of this gearing. lateral strain upon the axles of the ear is etfeetively avoided.

l. driving gear for a rail ear comprising an eleetrie motor and motor shaft nu-unted eentrally between the axles and longitudimilly to the ear: a bevel gear carried by the motor shaft: :1 bevel pinion meshing therewith and mounted on a countersbatt: a pinion mounted on said countershat't: and a gear engaging said pinion monntedon an axle of the 'ail'ear, the latter pinion and gear being in the median lane of the ear.

2. [u an eleetrie rail an a truck carrying a motor with its motor shaft lying in the anedian plane thereof. and provided with a bevel gear at eaeh extremity: countershafts with bevel gear meshing with each of such bevel gear. eaeh eountershaft being geared to an axle by gearing lying in the median plane of the truelt.

in testimony whereof, I have hereunto signed my name at Philadelphia, Pennsyb vania. this tenth day of February 1911.
